OpenStack Compute supports many hypervisors, which might make it difficult for
|
|
you to choose one. Most installations use only one hypervisor. However, you
|
|
can use :ref:`ComputeFilter` and :ref:`ImagePropertiesFilter` to schedule
|
|
different hypervisors within the same installation. The following links help
|
|
you choose a hypervisor. See :doc:`/user/support-matrix` for a detailed list
|
|
of features and support across the hypervisors.
|
|
|
|
The following hypervisors are supported:
|
|
|
|
* `KVM`_ - Kernel-based Virtual Machine. The virtual disk formats that it
|
|
supports is inherited from QEMU since it uses a modified QEMU program to
|
|
launch the virtual machine. The supported formats include raw images, the
|
|
qcow2, and VMware formats.
|
|
|
|
* `LXC`_ - Linux Containers (through libvirt), used to run Linux-based virtual
|
|
machines.
|
|
|
|
* `QEMU`_ - Quick EMUlator, generally only used for development purposes.
|
|
|
|
* `VMware vSphere`_ 5.1.0 and newer - Runs VMware-based Linux and Windows
|
|
images through a connection with a vCenter server.
|
|
|
|
* `Xen (using libvirt)`_ - Xen Project Hypervisor using libvirt as
|
|
management interface into ``nova-compute`` to run Linux, Windows, FreeBSD and
|
|
NetBSD virtual machines.
|
|
|
|
* `XenServer`_ - XenServer, Xen Cloud Platform (XCP) and other XAPI based Xen
|
|
variants runs Linux or Windows virtual machines. You must install the
|
|
``nova-compute`` service in a para-virtualized VM.
|
|
|
|
* `Hyper-V`_ - Server virtualization with Microsoft Hyper-V, use to run
|
|
Windows, Linux, and FreeBSD virtual machines. Runs ``nova-compute`` natively
|
|
on the Windows virtualization platform.
|
|
|
|
* `Virtuozzo`_ 7.0.0 and newer - OS Containers and Kernel-based Virtual
|
|
Machines supported via libvirt virt_type=parallels. The supported formats
|
|
include ploop and qcow2 images.
|
|
|
|
* `PowerVM`_ - Server virtualization with IBM PowerVM for AIX, IBM i, and Linux
|
|
workloads on the Power Systems platform.
|
|
|
|
* `zVM`_ - Server virtualization on z Systems and IBM LinuxONE, it can run Linux,
|
|
z/OS and more.
|
|
|
|
* `UML`_ - User-Mode Linux is a safe, secure way of running Linux versions and Linux
|
|
processes.
|
|
|
|
* `Ironic`_ - OpenStack project which provisions bare metal (as opposed to virtual)
|
|
machines.
